A method for providing an image representation with a surgical microscope, includes capturing a color image representation of a capture region with a camera, capturing a fluorescence image representation of the capture region with a fluorescence camera, generating a detailed image from the captured color image representation with a spatial filter and an edge stop function, mixing the captured color image representation, the captured fluorescence image representation and the generated detailed image to form a mixed image representation, and providing an image signal which encodes the mixed image representation. Further, the disclosure relates to a surgical microscope.

To simplify the optical calibration of an optical observation apparatus, a stand for an optical observation unit including a calibration object arranged directly on the stand in a fixed location is specified. Moreover, an optical observation apparatus, which includes such a stand and an optical observation unit connected to the stand, a method for calibrating such an optical observation apparatus, and a computer program are specified.

A method for correcting a shading in a digital image of a three-dimensional observation object obtained by at least one image sensor of an optical observation device is provided. The three-dimensional observation object is illuminated by illumination light and an intensity distribution, and an inhomogeneity in an image brightness is present in the digital image of the three-dimensional observation object. The method includes ascertaining a topography of the three-dimensional observation object, correcting the inhomogeneity in the image brightness of the digital image based on the topography of the three-dimensional observation object and the intensity distribution of the illumination light. In addition, an optical observation system is provided to perform the method.
